Configuring Cdp Compatibility; Configuring Lldp Trapping - 3Com 4210G Series Configuration Manual

Configuring CDP Compatibility

CDP-compatible LLDP operates in one of the follows two modes:
TxRx, where CDP packets can be transmitted and received.
Disable, where CDP packets can neither be transmitted nor be received.
To make CDP-compatible LLDP take effect on certain ports, first enable CDP-compatible LLDP
globally and configure CDP-compatible LLDP to operate in TxRx mode.
Follow these steps to enable LLDP to be compatible with CDP:

Enter system view

mode
As the maximum TTL allowed by CDP is 255 seconds, ensure that the product of the TTL multiplier
and the LLDPDU transmit interval is less than 255 seconds for CDP-compatible LLDP to work properly
with Cisco IP phones.

Configuring LLDP Trapping

LLDP trapping is used to notify the network management system (NMS) of events such as new
neighboring devices detected and link malfunctions.
To prevent excessive LLDP traps from being sent when topology is unstable, you can set a minimum
trap sending interval for LLDP.
